Patrick Tate Adamiak is a Navy veteran, a son, a brother, a collector of military memorabilia, and federal prisoner No. 95252-509. He is starting his fifth year of a 20-year sentence after being convicted of violating federal gun laws.

Lawyers for the former Navy SEAL candidate are preparing to ask a U.S. District Court judge to reconsider Adamiak’s sentence at some point in the future. The attorneys were hoping to present evidence they say shows agents with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) lied during Adamiak’s trial.
